No pet-bar verb asked whether the pet's actions were usable. So a stunned, feared or confused pet, a pet out of view, a pet that is not yours, or a charmed player still did all of this:
- pressed, latched Stay, Follow and the reactions, and swept the GCD;
- sent `CMSG_PET_ACTION` and flipped autocast;
- showed `GetPetActionsUsable()` as 1, which kept the stock bar in colour.
`0x4bcf70` is the reference's one predicate. It returns 0 in any of these cases:
- the active player does not resolve (`0x4bcf92`);
- the player is charmed (`0x4bcf98`-`0x4bcfa4`);
- the player's far-sight guid (`PLAYER_FARSIGHT`) is set and is not the pet (`0x4bcfbf`-`0x4bd012`);
- the pet guid does not resolve to a unit (`0x4bd034`-`0x4bd03d`);
- the pet's charmed-by guid, else its summoned-by guid, is not the player (`0x4bd03f`-`0x4bd067`);
- the pet is stunned, confused or fleeing (`0x4bd06f`-`0x4bd08b`);
- bar-state bit 27 is set (`0x4bd08d`).
These callers ask it:
- `GetPetActionsUsable` (`0x4be0b3`);
- the dispatcher behind `CastPetAction`, the orders and Dismiss (`0x4bd1f2`, before its type switch);
- `TogglePetAutocast` (`0x4bcbcf`);
- the pet book's toggle (`0x4bccce`);
- the bar write used by the drag's drop and the pickup's blank (`0x4bc9d0`).
Changes:
- `ui_pet/usable.rs` builds `0x4bcf70` once. The bar's feed pushes it as `GetPetActionsUsable`. `PetPress::press` asks it first, before the aura cancel.
- Both autocast drains, Dismiss and the drag's two writes ask it too. A pickup still lifts the action onto the cursor, as the reference does.
- The spell arm's later player and pet lookups, and the Attack arm's null branch, repeat the predicate's, so their dead handling goes.
- `arm_pet_gcd`'s doc now names the three places the pet's GCD starts: the press (`0x4bd36e`), a pet-addressed `SMSG_SPELL_COOLDOWN` (`0x6e9598`) and the generic cast send (`0x6e58fb`).
Tests:
- `ui_pet/usable_tests.rs` tries each of 11 exits alone, and 5 usable lookalikes, against `GetPetActionsUsable`, a spell press, the orders, both autocast toggles, Dismiss and the drag.
- A stock-UI test loads the default UI. A stunned pet's icon desaturates, and a click sends nothing until the stun ends.
- The three press tests that pinned ungated sends are flipped.
